Facebook CEO's sister Randi Zuckerberg has book deal

HarperCollins announced Wednesday that Randi Zuckerberg plans a memoir and a children's book. The social media executive and entrepreneur left Facebook in 2011.

Her memoir, "Dot Complicated," is scheduled for release Nov. 5. It will combine personal and professional insights for the digital age, from her years as Facebook's marketing director to becoming a mother in 2011. "Dot Complicated" is also the name of her online newsletter.

Randi Zuckerberg has since founded her own Zuckerberg Media. She is known in part for opposing anonymity online, saying it enables cyber-bullying.

Her brother co-founded Facebook in his Harvard dorm room in 2004. His net worth is estimated at $9.4 billion.
